What clalm is:- 1. A driedr and separator of the character described comprising a series of superimposed and communicatingl compartments xeach made wlth an entrance and an exit for the material that is to be treated, the

exit of each compartmentexcept the last one of the series discharginginto the next compartment below it at a distant pointfrom the exitA of the latter; a shaft extending through all of vsaid compartments;v a1 rake' in-each compartment carried by said shaft, said rake having downwardly extending tines, `upwardly extending tines4 upon the iloor of each compartment between kwhich the tines of the rake of said compartment pass as' said rake rotates with the y shaft; 'means for driving said shaft; means for heating the material while it is passing through said compartments; `and means for drawinggoll' from said compartments the vapors given oiiI bysaid material.

Q. A rier of the character described c mof communicatmg and superimposed* cylindrical chambers each made with angularly off-set inlet and outlet; a'hotl` air jacket for each chamber, said 7 hot air jackets belng connected-'in series;

a hot air supply pipe connected with the outlet from the jacket at the other end of said series; a shaft extending through all of said chambers; means within each cham-- ber .and connected with said-shaft for moving the material' bemg'treated from the pomt 4where it `enters the chamber `to the of said series; an air outlet ofthe latter, and means for removiiiig fliom said chambers the vapors given o by the heated mmterial.

3. A drier of the character described comprising a plurality of communicating and superimposed cylindrical chambers each made with angularly 'off-set inlet and outlet; a hot air jacket for each chamber, said jackets being conne( ted in series; a hot air vsupplypipe connected with the jacket at one end of said seres; an air outlet communicating withthf jacket at the opposite end of said serien; a shaft 'i extending through all of said chambers; a rake within each chamber connected with said shaft; .rejections upon the interior of each chamer coperating with the rake thereof to break up the material; an outlet; communieating with one oi said chambers, and means'for drawingA off through said outlet the vapors.l or the like produced in the chambers.

4. A drier of the c iaracter described com?y prising a plurality of communicating and superimposed cylin irical chambers each made with an ularl;r oil-setA inlet and outlet; a hot airjacket for each chamber, said jackets being connected. in series; a h'ot air supply pipe connecied with the jacket at one end of said series; an air outlet Vcommunicating with the -jacket at the'opposite end of said series; Aa shaft extending through all of said c mmbers; a rakewithin each chambernconnicted with said" shaft;

an outlet for vapors and the like communieating with one of said chambers; means 4for drawing off through said outlet the vapors or the like produced in the chambers, a conduit connected with the inlet `of the uppermost chamber through which the material to be treated ie; su plied to the apparatus, and means normal Y closing said conduit but adapted to Je manipulated to permit ofthe entrance of fresh material, the

outlets of each two :.djoining chambers bcing angularly offset relatively so that 'the material makes nearly a complete circuit of each chamber befon it reaches the outlet thereof.
